Issue with DICOM File Size and Performance in Orthanc

Hello,

1.2.840.10008.1.2.4.50 indicates “JPEG Baseline”, which only supports 8bpp. You are presumably trying to encode a radiology image with 10bpp or 12bpp. In such a case, the Orthanc logs would contain a line such as:

W0525 09:36:24.212220          DICOM-1 DcmtkTranscoder.cpp:403] DCMTK was unable to transcode from 1.2.840.10008.1.2.1 to one of: 1.2.840.10008.1.2.4.50 Can not transcode to 1.2.840.10008.1.2.4.50 if BitsStored != 8

In addition, the option DicomToJpegTranscodingQuality does not exist. As indicated in the documentation, you are looking for option DicomLossyTranscodingQuality. Looks like yet another ChatGPT hallucination that wastes everyone’s time.

No, the DICOM standard does not support the embedding of DOC/DOCX files in a DICOM envelope. This is not specific to Orthanc. However, in Orthanc, you could use the “attachments” feature that allows you attach an arbitrary file (including DOC/DOCX) to a DICOM study, series, or instance.

Just a reminder: I already answered this same question from you two months ago.

Regards,
Sébastien-
